1-2 SOFTWARE POWER OFF CONTROL
The mainboard designs to support Software Power Off Control feature through the SMI
code in the BIOS under Windows 95/98, and MS-DOS operation system environment.
This is Intel ATX form factor feature and you should use ATX power supply.
First, you should connect the power switch cable (provided by the ATX case supplier)
to the connector “PS-ON” on the mainboard. In the BIOS screen of POWER
MANAGEMENT SETUP’, choose “User Defined” (or “Min. Power Saving” or “Max.
Power Saving”) in ‘Power Manager’ and choose “Yes” in ‘PM Control by APM’.
In Windows 95/98, if you would like to power off the system, you just choose
“shutdown the computer ?” in the “Shut Down Windows“ from Windows 95/98, then
the system power will be off directly, and become the stand-by status. You will find the
power LED light blinking. You have the to enable/disable power LED light blinking. If
you want to disable blinking, please set the Jumper of JP5 from default to 2-3 (close)
position. If you would like to restart the system, just press the power switch button, and
the system will be powered on.

1-3 SB-Link Sideband Signals
In order to migrate the legacy Sound Blaster compatible audio to the PCI bus,
EMU8008 incorporates a pair of SB-Link request/grant sideband signals (PCPCIR
EQN and PCPCIGNTN) to interface to the PCI bus. SB-Link is a mechanism that was
defined and developed by Creative as a docking solution which allows ISA slots to
exist in docking station, so it can be connected to desktop PC PCI bus.

1-4 Keyboard & PS/2 Mouse Power On (JP9)
The ATC-6230 mainboard built-in Jumper of JP9 may have two easily and conveniently
ways to power up the system. Users may power on the system by typing a password, or
power on the system by double-clicking the PS/2 mouse, when JP9 is 2-3 close.
In addition to satisfying different users will have many different needs, the ATC-6230
mainboard provides four different methods to power up the system:
1. KB Power On Password:
The following functions are available for ATX power only. User can select the
power on method to power on the system, by entering Award BIOS Setup
menu/Integrated Peripherals/Power On Function. The options are the following
:Password : when user select this option, it will show “Enter Password:”, after user
type password, it will show “Confirm Password:”, user should type the same
password to confirm it. After power off, if user types the correct password, the
system will power on.
2. Hot Key Power On:
When user select this option, it will show another line as Hot Key Power ON: Ctrl-
F1”’ select any one you like. After power off, if user key in the control-F, it will
power up the system.
3. Mouse Left, Mouse Right :
It will power up the system by double click the left or right mouse. Note do not
move your mouse between the first click and the second click.
4. BUTTON ONLY :
Only the power button can power the system.

1-5 Running 100 MHz CPU Bus on ATC-6230
mainboard (JP11)
ATC-6230 mainboard provides Jumper of JP11 where it allows you to set your CPU
host clock to perform the function of CPU overclock. There are two ways of option to
set CPU host clock which are ‘close’ and ‘open’. Set ‘close’ which the system will auto
detect the CPU host clock, i.e.66MHz and 100MHz. Another way is to set Jumper of
JP11 to ‘open’ which the system can be operated the higher CPU host clock than CPU
itself.
It is recommended that users should use Intel PentiumII (Deschutes) 100 MHz CPU,
running at 350, 400, 450 MHz interval clock speed. Moreover, the SDRAM memory
module should use 8 nano-second (Maximum Frequency 125 MHz) speed of memory –
die or less.
It is important to remember that the default setting of JP11 is ‘close’.

1-6 Wake-On-LAN
The remote Wake-On-LAN mode of operation is a mechanism that uses Advanced
Micro Device Magic Packet technology to power up a sleeping workstation on the
network. This mechanism is accomplished when the LAN card receives a specific
packet of information, called a Magic Packet, addressed to the node on the network.
For additional protection, Secure ON is an optional security feature that can be added to
the Magic Packet that requires a password to power up the sleeping workstation. When
the LAN card is in remote Wake-On-LAN mode, main system power can be shut down
leaving power only for the LAN card and auxiliary power recondition.
The LAN card performs no network activities while in the remote Wake-On-LAN mode
of operation. It only monitors the network for receipt of a Magic Packet. If a Magic
Packet is addressed to the LAN card on the network, the LAN card wake up the
system. If the Secure ON feature has been enabled, the password added to the Magic
Packet is also verified prior to waking up the system.
WOL LAN card will provide a 3-pin line to connect the WOL connector on the
mainboard.
CAUTION :
For Wake-on-LAN, the +5V standby line for the power supply must capable of
Delievring +5V ±5% at 720mA. Failure to provide adequate standby current when
implementing Wake-on-LAN, can damage the power supply.
Before you enable Wake-on-LAN function, first check your power supply specification
to meet the above requirement or not.

1-7 Thermister (option)
When setting up the thermister, the BIOS will load the CPU temperature automatically.
There is a choice of the warning beep sound if the user set the option on. If the CPU
temperature overheated, the user will get the notice from the thermister. This time you
should shut down computer and check your devices. Or you can connect with you
dealer.
Therefore, protecting and monitoring the CPU temperature is the thermister’s job.

CHAPTER 2 INSTALLATION
2-1 INSTALLATION PROCEDURE
Before installing the computer, please prepare all components such as CPU, DRAM;
peripherals such as hard drive, keyboard, CD-ROM; and accessories such as cables.
Then, install the system as following:
1. Plug CPU/ heat sink (refer to Pentium II installation guide, Appendix A), and
DRAM modules on the mainboard.
2. Set DIP switch based on your configuration.
3. Plug add-on cards into PCI/ISA slots, if needed.
4. Connect the power supply.
5. Connect I/O and other cables to the system, especially for Sound connector.
6. Make sure all components and devices are well connected, turn on the power and
setup System BIOS based on your configuration.
7. Install peripheral devices, add-on card drivers and test them.
If all of above procedures are running successfully, turn it off and screw the chassis
cover to the system, and then connect external devices which are cabled to the system.
